. ATTORNEY Patented Apr. 13, 1943 CARD CLOTHING Ernest L. Cady, Hartford, Conn, assignor to The E. L. Cady Engineering Company, West Hartford, Conn., a corporation of Connecticut Application June 18, 1941, Serial No. 398,607

3 Claims.

This invention relates to card clothing and particularly to the arrangement of the wire staples inserted within and extending from a surface of the band or ring forming the foundation of the clothing so that a transverse opening across the clothing will be formed between adjacent rows of needles.

An object of primary importance of the invention is that the staples are so placed that the opposite ends of the staples forming the needles extend in spaced transverse rows disposed at right angles to the length of the band, one end of the staple wire forming a needle being in one row and the opposite end of the same wire forming a needle being in an adjacent row, these ends being bent at an oblique angle to the central portion of the staples.

Another object of the invention is to form card clothing particularly adapted for carding machine doifer rings in which interposed radially movable members extending generally transversely of the band may be inserted between the needles to facilitate the removal of the fibres from the rings of the doffer roll.

Another object of the invention is to group alternately transversely disposed staples arranged in overlapping longitudinally extending rows with the central portions of each of the staples extending obliquely of the band, and with the openings through the band through which the opposite ends of the staples extend being uniformly spaced both longitudinally and transversely of the clothing band.

With the above and other objects in view the invention includes the features of construction and operation set forth in the following specification and illustrated in the accompanying drawing.

In the accompanying drawing annexed hereto and forming a part of this specification, I have shown the invention embodied in a form of card clothing adapted primarily for doifer rings of textile carding machines but it will be understood that the invention can be otherwise embodied and that the drawing is not to be construed as defining or limiting the scope of the invention, the claims appended to this specification being relied upon for that purpose.

In the drawing:

Fig. 1 is an underside plan view of a length of card clothing made according to the present invention with some only of the needles shown in position; 7

Fig. 2 is an enlarged view in side elevation of the card clothing shown in Fig. 1; I

Lil

Fig, 3 is a transverse sectional view of the clothing shown in Fig. 2 but upon a still larger scale, the section being taken on a plane parallel to the line 3-3 in Fig. 2;

Fig. 4 is an enlarged sectional view in eleva-' tion taken longitudinally along the length of the card clothing shown in Figs. 1 and 2, upon the plane of line 44 in Fig. 1; and

Fig. 5- is an enlarged sectional view taken upon the plane of line 55 in Fig. 1.

In the above mentioned drawing there has been shown but one embodiment of the invention which is now deemed preferable, but it is to be understood that changes and modifications may be made within the scope of the appended claims without departing from the spirit of the invention.

Briefly, and in its preferred aspect, the invention may include the following principal parts: first, a band of leather or other flexible material of suitable width and having sufficient thickness to provide a substantial support and foundation for the needles; second, bent wire staples having their opposite ends bent into parallelism and extending through the band to form fibre removing needles.

Referring more in detail to the figures of the drawing there is shown at H! a length of band forming the foundation for the card clothing or dofiing ring. This material It may be of any flexible but firm material usually employed for this purpose. Extending through this material II] are the staples H the opposite ends II of which project obliquely and in parallel rows from the material l0. Each needle l2 lies in a plane normal to the surface of the material In, these normal planes extending longitudinally along the length of the clothing. Fig. 2 shows the oblique angle which the needles make in the direction of the length of the clothing and Fig. 3 shows the right angle or normal position of the needles transversely of the clothing Ill. The central portion of the staple I l lies against the underside of the clothing II] which in use closely surrounds a drum or roll (not shown).

By an inspection of Fig. l the disposition of the staples I l relative to each other will be seen. The apertures l3 through the material ill for the staples II are uniformly spaced apart both longitudinally and transversely of the material. The longitudinal rows of staples II, as viewed from the underside of the band material ID, are staggered or alternately overlap each other and the central portion of the staple lies obliquely against the material I!) of the band.

Each staple, as best shown in Fig. 5, has its central portion disposed at an oblique angle to its opposite end portions forming the needles. The end portions of each staple lie in a common plane and are parallel to each other so that each end portion stands at a corresponding oblique angle to the central portion. This oblique angle between the end portions of a staple and its central portion is required due to the fact that the needles are inclined longitudinally of the band as seen in Fig. 2 and also because each staple is disposed with its central portion disposed obliquely relative to the length of the band as seen in Fig. 1.

I claim as my invention:

1. Card clothing comprising a strip of flexible material having staples supported therein the opposite ends of which are disposed at oblique angles to the central portion and which extend through said strip to form needles, said staples being individually disposed obliquely relatively to said strip and grouped in transversely overlapped longitudinally extending rows suitably spaced to provide open transversely extending spaces of uniform width.

2. Card clothing comprising a strip of flexible material having staples supported therein the opposite ends of which are disposed at oblique angles to the central portion and which extend through said strip to form needles, said staples being individually disposed obliquely relative to said strip and grouped alternately in transversely overlapped longitudinally extending rows suitably spaced to provide open transversely extending spaces of uniform width.

3. Card clothing comprising a strip of flexible material having staples supported therein the opposite ends of which are disposed at oblique angles to the central portion and which extend through said strip to form needles, said staples being individually disposed obliquely relative to said strip and grouped alternately in transversely overlapped longitudinally extending rows suitably spaced to provide open transversely extending spaces of uniform width, and the ends of each staple being disposed in different transverse rows of needles.
